Fetal Bovine Serum specific

• Fetal Bovine Serum, Tetracycline Negative

Serum is the blood component that can be obtained after coagulation and by removing cellularcomponents. Besides serum proteins it contains, e.g. growth factors, amino acids and hormones. Thiscomprehensive mix makes serum one of the most important supplements, supporting cells to grow andproliferate in vitro cell culture. Of special interest is the fetal bovine serum (FBS). It is especially rich ingrowth factors and is particularly low in antibodies, which may influence the cell culture work.

Capricorn Scientific has established a test with an external test laboratory, using liquidchromatography tandem mass spectroscopy to detect all kinds of tetracycline. This method allows anaccurate detection of Chlortetracycline and the Oxytetracycline in a range of 0.05 mg/l.

• Fetal Bovine Serum ES Cell Pretested

Embryonic stem (ES) cells are particularly demanding and it is crucial to keep them in theirvaluable undifferentiated state. When working with stem cells maintenance of pluripotency and reduceddifferentiation are the main objectives. Historically, EC cell researchers were required to screenlaboriously several lots of serum to find one suitable for their cells. Capricorn Scientific offers ES CellPretested FBS to minimize the need for prescreening serum, saving both time and money, whileproviding the assurance that the serum used has been screened by experienced ES cell culturists.
